¶ … light bulb was perhaps the most significant invention since fire; although fire was never truly invented. Nevertheless, the light bulb has impacted our lives on a scale similar to that of when our ancestors first harnessed the flame: it has altered the way people live their lives so drastically that it is difficult to even imagine life in its absence. Thanks to its invention, the night is open to far more activities than the candle or even the lantern could ever have provided. Its likelihood as a fire starter is much less than its predecessors, thus increasing the safety of people and their property. The light bulb has changed the face of travel. It has also greatly increased productivity worldwide. Additionally, the invention of the light bulb proved the value of electricity and suggested that many and far more varied devices could be produced which continue to change the way people work, play, relax, and live to this very day. The light bulb has done far more than just provide the world with a better way to read the evening paper.
Before the light bulb, one of the most viable options for lighting a home was the candle: "Candles, of course, were a big success. They achieved their current form in the seventh century and did the job so well that they were still in widespread use for lighting a century ago."
One obvious drawback to the candle, however, was that it could not light an entire room. The answer to this came with the lantern; yet this could be expensive and even more dangerous. But the widespread distribution of the light bulb simultaneously solved both of these problems and permitted many more nighttime activities. Reading and writing from electric light proved to be much easier; so accordingly, important work that could previously have only been completed during daylight hours spilled over into the night. Cooking, cleaning, schoolwork, and nighttime recreation all became vastly easier with the advent of the light bulb. Naturally, this is not to say that these activities were impossible without the light bulb, but it did make them simpler, and therefore, they were done more often.
As aforementioned, another change ushered in by...
For many people, global warming is primarily relevant to them in regards to the weather. They assume that when it is excessively hot, this is reflective of a shift in the global climate and when it is cold, this is a sign that global warming is not really as bad as it might be. However, this is far from the truth. While changes in weather may still be present during
Real trial-based evidence shows a clear success in reduced cracking in cement which is reinforced thusly. Our research tells that these reinforces cement bodies "have aspect ratios of 500 or more and diameters - about the same size as the distance between layers in hydrated cement - so that cracks in the matrix would quickly encounter well-dispersed SWCNTs, inhibiting their growth." (Makar, 1) In order for these findings to be used in any real-world setting,
The Principles of Machiavelli in American Policy The first chapter in The Practice of American Public Policymaking lays out what the book examines in the succeeding chapters. First, Briggs and Helms (2015) define policymaking as “the activities, actors, institutions, practices, and technologies that combine to ‘deliver the goods’ to the American people” (p. 3). Public policy is defined as “the art and science of producing results” (p. 3). Thus, the book
An additional negative aspect can occur when a seemingly green product really isn't, in the long run. As an example, one of the most successful 'green' vehicles is the Toyota Prius. The hybrid Prius has become the status symbol for all of those wishing to flaunt their environmental conscience. However, the vehicle isn't nearly as eco-friendly as the Green Marketing campaigns lead consumers to believe. The nickel metal hydride battery
